This UK company makes them
Insulated water tanks
And from that site I have copied this
"Enduramaxx’s Insulated
Water Tanks are designed for use where temperature regulation is key and for the prevention of overheating or freezing of liquids.
This drinking water tank is available in 27 different capacities from 150 litres up to 40,000 litres.
These single skin self-supporting plastic tanks are tough, durable, impact-resistant and suitable for the storage of a wide range of liquid chemicals.
Constructed from rotationally moulded mid-density UV stabilised food-grade polyethene which is wrapped in a jacket constructed using an insulation system engineered to prevent condensation and effectively reduce thermal and
energy loss.
WRAS Approved Insulated Tanks
Our insulated water tanks are all fully DWI approved and meet the specific requirements of Regulation 31.
The Drinking Water Inspectorate (DWI) under the umbrella of the UK Government’s DEFRA (Department for Environmental, Food and Rural Affairs) states that;
“Protection of public health of consumers through safeguarding the quality of drinking water is a key aspect of the drinking water quality regulatory framework”
Regulation 31 ensures that water suppliers, when producing and distributing drinking water, only use products and substances that do not cause any
detrimental effects on the safety or quality of the drinking water."
OK nobody will shift a tank from Britain, but it can be done and deserves investigation locally.
